26 Wave length & Amplitude the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

27 Wave length & Amplitude the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

28 Types of Sound Waves  Longitudinal: Like P-waves  Mechanical: Like Surface Waves (ex: water)  Transverse: Like S-waves  Types of Waves INFO Types of Waves INFO

33 Pitch The sensation of a frequency is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave

34 Doppler Effect  The Doppler effect is the change in frequency of a wave (or other periodic event) for an observer moving relative to its source

35 Ear Diagram & Info  anvil - (also called the incus) a tiny bone that passes vibrations from the hammer to the stirrup.  cochlea - a spiral-shaped, fluid-filled inner ear structure; it is lined with cilia (tiny hairs) that move when vibrated and cause a nerve impulse to form.  eardrum - (also called the tympanic membrane) a thin membrane that vibrates when sound waves reach it.  Eustachian tube - a tube that connects the middle ear to the back of the nose; it equalizes the pressure between the middle ear and the air outside. When you "pop" your ears as you change altitude (going up a mountain or in an airplane), you are equalizing the air pressure in your middle ear.  hammer - (also called the malleus) a tiny bone that passes vibrations from the eardrum to the anvil.  nerves - these carry electro-chemical signals from the inner ear (the cochlea) to the brain.  outer ear canal - the tube through which sound travels to the eardrum.  pinna - (also called the auricle) the visible part of the outer ear. It collects sound and directs it into the outer ear canal  semicircular canals - three loops of fluid-filled tubes that are attached to the cochlea in the inner ear. They help us maintain our sense of balance.  stirrup - (also called the stapes) a tiny, U-shaped bone that passes vibrations from the stirrup to the cochlea. This is the smallest bone in the human body (it is 0.25 to 0.33 cm long).

36 Electromagnetic Waves  Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.

37 Polarized Light Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization. Polarizing Light Video

38 Photoelectric Effect  The photoelectric effect is the observation that many metals emit electrons when light shines upon them. Electrons emitted in this manner can be called photoelectrons.

39 Photon  Photons are tiny little particles of light, far too small to see individually

40 Thermogram an instrument that produces a trace or image representing a record of the varying temperature or infrared radiation over an area or during a period of time.

41 Electromagnetic Spectrum  The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation

42 Visible Light Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 700 nm -See previous slide for spectrum

43 Ultraviolet Rays  Radiation in the part of the electromagnetic spectrum where wavelengths are just shorter than those of ordinary, visible violet light but longer than those of x- rays.

44 X-Rays -an electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials opaque to light.

45 Gamma Rays  penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei.

46 Amplitude modulation  the modulation of a wave by varying its amplitude, used chiefly as a means of radio broadcasting, in which an audio signal is combined with a carrier wave.

47 Frequency Modulation  the modulation of a radio or other wave by variation of its frequency, especially to carry an audio signal.
